Molecular Sieve 5Ais an alkali alumino silicate; it is the calcium form of the Type A crystal structure. Type 5A has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger.It is especially suitable for PSA adsorber applications where it may be used for theseparation of normal- and iso- paraffins (C4 to C6 species),in PSA hydrogen purification and in oxygen concentrators.

Molecular formula: 0.4K2O · 0.6Na2O · Al2O3 · 2.0SiO2 · 4.5H2O
